SNVSBJ4A April 2020 – September 2020 LM25183-Q1
PRODUCTION DATA
The input capacitor filters the primary-winding current waveform. To prevent large ripple voltage, use a low-ESR ceramic input capacitor sized according to Equation 25 for the RMS ripple current given by Equation 26. In this design example, choose a 10-µF, 50-V ceramic capacitor with X7R dielectric and 1210 footprint.
